Gymnopilus picreus
Local name: Dunkelstieliger Flämmling
Dunkelstieliger Flämmling (Gymnopilus picreus) is a distinctive mushroom species characterized by its rusty-orange to yellow-brown cap and notably dark stem that gives it its German common name. This saprobic fungus plays a crucial ecological role in forest ecosystems by decomposing dead hardwood, particularly beech and oak, helping to recycle nutrients back into the soil.

Species Profile
Dunkelstieliger Flämmling (Gymnopilus picreus) is a distinctive mushroom species characterized by its rusty-orange to yellow-brown cap and notably dark stem that gives it its German common name. This saprobic fungus plays a crucial ecological role in forest ecosystems by decomposing dead hardwood, particularly beech and oak, helping to recycle nutrients back into the soil.
Dunkelstieliger Flämmling faces significant threats from habitat degradation and loss of suitable forest ecosystems across its range. Climate change and altered precipitation patterns are affecting the delicate moisture conditions required for this fungal species to fruit and reproduce successfully.
Key Facts
Habitat & Distribution
This saprophytic fungus inhabits temperate and boreal coniferous forests, particularly growing on decaying wood of spruce, fir, and pine trees. It requires specific moisture conditions and is typically found in mature forest ecosystems with abundant deadwood substrate.
Threats
Climate change affecting moisture regimes
Forest habitat degradation and fragmentation
Air pollution and acid deposition
Intensive forestry practices
Loss of suitable host tree species
